+NB. : you should **make sure that your user is in the `lxd` group** so that it's
+able to run `lxc` commands without sudo... You can check this with the command
+`groups` where you should see `lxd`. Otherwise, add your user to this group
+(don't forget that you may need to reload your entire graphical session for this
+to propagate (sigh))
+
 Then you shall initialize LXD which will ask you a bunch of question. Usually
 answering the default (just pressing enter) to all questions is fine.
